EGG-CASE.

SPECIFICATION forming part of Letters Patent No. 375,363, dated December27, 1887.

Application filcd May 7, 1887. Serial No. 237,390. (No model.)

two series of paper-board or analogous partitionstrips, with thepartition-strips of one series arranged to intersect the severalpartitionstrlps of the remaining series, the whole forming a frame whichcan be brought into rectangular form when in use, and when not in useclosed, so as to cause all of the partition-strips to lie substantiallyparallel with one another and closely together.

A simple and approved mode of connecting together the two sets or seriesof partitionstrips at all points of intersection, excepting along thefour sides of the frame, has consisted in slitting each strip-at severalpoints transversely to its length and for a portion of its width, andconnecting the slitted strips of one set with those of the remaining setby'interlocking the strips at the points Where thecuts or slits aremade,it being understood thatthe slots or slits in the strips of one setreceive unslitted portions of the strips of the other set, which latterin turn similarly engage the strips of the set first mentioned. It is,however, desirable, and in fact a matter of necessity, to provide othermeans for looking to gether the strips at the points of intersectionalong the four sides of the frame, since, should the foregoing mode ofinterlocking the strips at several points between their ends be employedat points along the four sides of the frame, the structure would whenhandled be points along the sides of the frame by a form of jointattained by providing in one strip an angular or L-shaped slit, formedintermediate of the longitudinal edges of the strip,

found to such means in that the bendingof the paper-board frequentlycracks and weakens the same to such an extent that the end portion willduring use separate from the strip along the line of bend, therebypermittingthe structure to become disjointed, and hence impairing theefficiency and utility of the device.

The object of my invention is to provide a simple, durable, andefficient construction and disposition of parts, serving to avoid theforegoing-mentioned defects and to producea more desirable and reliablearticle, which can be readily put together, and which,when put together,will withstand all ordinary usage with out breakage.

To the attainment of these and other useful ends my invention consistsin matters hereinafter described, and particularly pointed out in theclaims.

In the drawings, Figure 1 represents in perspective a portion of anegg-carrier constructed in accordance with my invention. Fig. 2represents one of the three forms or constructions of strips involved inthe formation of my improved egg-oarrier. Fig. 3 represents the secondof said three constructions of strips herein present. Fig. 4 representsthe third construction of strip.

The egg-carrier consists of a rectangular frame, (whereof aportion isshown in Fig. 1,) said frame being composed of two series of strips,with the strips of one series arranged transversely to the strips of theother series, so as to provide a suitable nest of egg-holdingcompartments. These strips are connected together in the usual way atall points of intel-section excepting along the four sides of the frameand at the four corners thereofthat is to say, the strips of one seriesare slitted transversely for a portion of their width with the slits allcommencingalong one longitudinal edge of the strip,while thecorresponding slits of the strips of the remaining series commence atthe opposite longitudinal edges thereof, as will be understood byreference to Fig. 1. In this figure, omitting the two side stripstherein shown, the strips of one series are provided with transverseslits all commencing at points along the top edges of the strips, whilethe strips of the other series are provided with slits all commencing atpoints along their lower edges. The strips of each of these two seriesinvolve, however, different forms or constructions, while the fourstrips which form the sides of the frame involve still another or thirdform or construction. These three constructions can be best explained byreference to the last three figures, wherein B, Fig. 2, indicates one ofthree forms or constructions of cross-strips; C, Fig. 3, the second forminvolved in the construction of crossstrips, and D, Fig. 4., the form orconstruction of side strip.

It will be seen that the strip B is provided between its ends with aseries of transverse slits, 1), commencing at points along onelongitudinal edge of the strip and cut into the strip, so as to extendpartially across the width of the same, but that the strip is providedadjacent to each end with a transverse slit, 1), extending partiallyacross the width of the strip and commencing at the longitudinal edge ofthe strip that is opposite the longitudinal edge whereat the transverseslits b have their points of commencement or open ends. The two cornersof the strip B, at the points where the slits 1) occur, are alsodesirably cut off, substantially as shown, to facilitate the connectionof the ends thereof with certain other strips.

The strip 0 is provided at intervals along its length with thetransverse slits c commencing at points along one of its longitudinaledges and extending partially across the width of the strip. This strip0 is at each end pro vided with a short straight rectangular tongue, 0',extending out from the strip midway of its longitudinal edges.

The strip D is at each end slitted similar to the strip B, whereby it isprovided with the two end slits, (1, one at each end. The strip D is,however, between its slitted ends provided with short transverse middleslits, d, alternating with transverse edge strips 61 -43112? is to say,each middle slit, (1, is located midway between the longitudinal edgesof the strip and at its ends terminate short of such edges, while theslits d commence at points along one edge of the strip and extendpartially across the width of the same. These transverse slits d alsocommence at points along the longitudinal edge that is opposite the edgewhereat the transverse slits d commence, in which way the strip D is tosome extent similar to the strip B, the points of difference being thatin the strip B the transverse slits b somewhat outnumber thecorresponding slits, d in the strip D, and, further, that the strip lastmentioned is provided with the middle transverse slits, d, which areabsent in the strip B.

Referring more particularly to F1 g. 1, 1t w ll be seen that the twoside strips, D, therein shown are of the construction shown in Fig. 4.It will also be understood that in the complete frame each of the fourside strips consists of a like strip, D. The remaining strips which goto make up the body of the frame arearranged to constitute two series,with the strips of one series intersecting those of the other series. Inthis arrangement each series comprlsesa number of strips, B, like thestrip shown in Fig. 2, and a number of strips, O, like the strip shownin Fig. 3, these said strips being in each of the two series arranged toalternate with one another. The slits b of the strips B receive theunslitted portions of strips 0 that are in line with the slits c of thelatter, while on the other hand the slits c of the strips 0 receive likeunslitted portions of the strips B, so as to provide ordinary joints atsuch polnts of intersection. After the strips B and C have been thusinterlocked, so as to providea partially-completed frame, the four sidestrips, D, are to be applied to bring the frame to a state ofcompletion. When the side strips, D, are thus applied, these said stripsD w1ll interlock with the strips B along the hues of the slits d in theformer and the slits b in the latter, while the tongues c of the strips0 will be inserted through the middle slits, d, of the strips D. Thefour side strips, D, wlllalso 1nterloek with one another at the fourcorners of the frame, the interlocking of said strips being along thelines of their end slits, d. In this way the several parts of the frameWill be held together and prevented from falling apart, it being seenthat under such arrangement, first, the joints formed by reason of theslits b in the strips B and the slits d in the strips D are the reverseof the joints formed by the slits b of strips B and the slits c of thestrips 0; secondly, that the ends of the strips B included in one seriesof cross-strips engage one of the side strips, D, (shown in Fig. 1,)just the reverse of the engagement with the other side strip, D, of thestrips B of the other series of cross pieces; tongues c of strips 0alternate with the strips B in engaging the side strips, D; finally,that the strips D engage one another just the reverse of the engagementof the strips B with said strips D.

It will be understood that by the feature of interlocking the strips byarranging some of the slits to commence, say, at the top longitudinaledges of the strips and others to commence at what may then be regardedas the bottom edges of the strips, greater security is attained than ifthe disposition of slits were uniform throughout, and that the featuresof the straight tongues of certain of the crossstrips engaging instraight slits of the four side strips serves to hold the parts of theframe sethirdly, that the rectangular curely together, and at the sametime to constitute an exceedingly simple and efficient means for sodoing.

What I claim as my invention is-- 5 1. An egg-carrier consisting of theside strips interlocking with one another at the corners of the frame,combined with the two series of cross strips forming the main bodyportion of the frame and comprising strips which are slit transverselyfrom their edges to interlock with the side strips at points where thelatter are similarly slitted, and strips provided at their ends withstraight tongues that are inserted through straight slits formed betweenthe longitudinal edges of the side strips,

substantially as shown and described, and for the purpose set forth.

2. In an egg carrier of the character set forth, the side strips, D, ofthe frame, each provided with transverse end slits, d, and transverseslits d cut. into the strips respectively from opposite longitudinaledges thereof, and further provided with middle slits, d, terminatingshort of the said longitudinal edges, combined with the two series ofcross-strips, each composed of strips B and strips 0, whereof each stripB is provided with transverse end slits, I), cut into the strip from onelongitudi-. nal edge, and intermediate transverse slits I), cut into thestrip from the opposite longitudinal edge, and each strip 0 provided ateach end with a straight tongue, 0, and between its ends provided with aseries of transverse slits, said members being fitted together andorganized substantially as described.
